Scalar RMs give no justification for their scores. Generative RMs explain their verdicts, yet their reasoning is often shallow. The authors treat preference judgment as a reasoning problem and introduce Reasoning Reward Models… 2. **[MEMORYLLM: Towards Self-Updatable Large Language Models](https://md.research.elamur.ai/free/en/papers/wang-2024-memoryllm-towards-self-updatable-large/)** *(2024 · 27 citations)* Large language models are usually frozen once deployed, which makes adding fresh knowledge difficult. Current workarounds each have drawbacks. Retrieval stores keep growing, fact-level editing struggles with longer passages, and long-context approaches eventually run out of context length. This paper proposes… 3. **[Current Agents Fail to Leverage World Model as Tool for Foresight](https://md.research.elamur.ai/free/en/papers/qian-2026-current-agents-fail-leverage-world/)** *(2026 · 1 citation)* The paper asks whether today's vision-language agents can treat a generative world model as an optional external tool: a simulator they consult to preview the consequences of an action before committing to it in the real environment. 4. **[Beyond Sample-Level Feedback: Using Reference-Level Feedback to Guide Data Synthesis](https://md.research.elamur.ai/free/en/papers/mehri-2026-beyond-sample-level-feedback-reference/)** *(2026)* Synthetic instruction-tuning data is cheap to produce, but a model trained on it usually cannot exceed the LLM that generated it. ## Co-authors here 12 of 28 co-authors with a page, the most papers together first. - [Heng Ji](https://md.research.elamur.ai/free/en/authors/heng-ji/) ×3 - [Cheng Qian](https://md.research.elamur.ai/free/en/authors/cheng-qian/) ×2 - [Dilek Hakkani-Tür](https://md.research.elamur.ai/free/en/authors/dilek-hakkani-tur/) ×2 - [Yu Wang](https://md.research.elamur.ai/free/en/authors/yu-wang/) ×2 - [Bing Yin](https://md.research.elamur.ai/free/en/authors/bing-yin/) - [Bingxiang He](https://md.research.elamur.ai/free/en/authors/bingxiang-he/) - [Bingxuan Li](https://md.research.elamur.ai/free/en/authors/bingxuan-li/) - [Bowen Jin](https://md.research.elamur.ai/free/en/authors/bowen-jin/) - [Denghui Zhang](https://md.research.elamur.ai/free/en/authors/denghui-zhang/) - [Emre Can Acikgoz](https://md.research.elamur.ai/free/en/authors/emre-can-acikgoz/) - [Gokhan Tur](https://md.research.elamur.ai/free/en/authors/gokhan-tur/) - [Hanghang Tong](https://md.research.elamur.ai/free/en/authors/hanghang-tong/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [Conference of the European Chapter of the Association for Computational Linguistics (EACL)](https://md.research.elamur.ai/free/en/venues/eacl/): [EACL 2026](https://md.research.elamur.ai/free/en/venues/eacl/2026/) ## Cited by Papers of our library cite their works 71 times (of the 149,439 papers whose bibliographies we read); [30 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/xiusi-chen/cited-by/).
